GAS-PRESSU RE REGULATOR.

SPECIFICATION forming part of Letters Patent No. 313,846, dated` March 17, 1885. Application filed October 14,1284. (No model.) l

.To aZZ whom'zt may concern:

Beit known that I, JOHN D. AVEEELL, a citizen of the United States oi' America, and a resident of the city of Brooklyn, in the county of Kings and State ofNew York, have invented a new and useful Improvement in Gas-Pressure Governors, of which the following is a specification.

The liquid governor is preferable to the diaphragm and others on account of its greater aocuracy and durability. In the mercury governor the expense for mercury renders the same expensive, the mercury oxidation accumulating and attaching to the inverted ioating cups gradually changing the regulated position ot' the governor-valve; and in said governor, with a very short movement, the valve requires from a closed to a full opening and is made in consequence very flat. All governors are most conveniently attached to the gas-connection if their inlets and outlets are arranged close near one another and in line above one another.

In the governor with my improvement glycerine-oi1 is substituted for mercury, and the governor-valve is attached to a closed bottom iioat resting in the oil, which is contained in a siphon-chambered case, and the position of the governoryalve to its seat is regulated by the gas-pressure upon the level of the oil in the arm or leg of the siphon in which the said iioat is employed. The outer arm or leg of the case may continue around the inner leg containing the iioat, thus forming two compartments or cases; but the form shown I prei'er. The valve is made with a long cone, and its closing and opening is better graduated than the flat-shaped valve above described. The inlet and outlet of the governor in my construction are arranged close to each other and in line one above the other for the most convenient application to gas-connection.

late the valve, the construction and arrangement of the parts being adapted to collect and prevent any matter that is condensed in the pipes from mingling with the glycerine, there being means provided for withdrawing such matter from the siphon gaspipe; also by this construction a sensitive and superior pressureregulating governor is produced at a comparative small expense. y

Said invention consists, also, in a novel construction of the governor-valve with a guiderod having a stopping-stud, and with an adjustable guide for said rod and a slot for said stud, so that by these means said valve is very freely and accurately guided in its motion to and from its seat, and by means of said slot and stud the valve may be at any timepput quickly in operation or entirely out of action, as if the governor were removed from the gasconnection, as is frequently required in testing the saving of gas.

Figure l represents a side elevation of the governor with my improvements. Fig. 2 is avertical sectional front elevation of the same, showing the front cover of the governoncase removed. Fig. 3 is a detached side view of the valvevrod and the guide oi' the same.

A represents the governor-case, and B its top cap. C is the governor-valve attached and governed by the float D. The valve C has its seat at the top or outlet opening, E, of the gas-conducting pipe F.

The case A is constructed with a U or vertical siphon, tubular-shaped, or vertical two legged chamber G, in which glycerine-oil is employed as a regulating-liquid to float the governor-valve and balance it over its seat and keep a normal pressure of gas passing from the governor. The space N in the iirst leg above the liquid of the chamber G, in which the float and valve are employed, is connected by a passage, H, with the dischargepipe H of the governor. The space I, over the liquid in the secondary portion or leg of ICQ the other, to provide for very ready and convenient connection with the gas-meter or other gas-connection of the place or building to which the governor is applied; and in consequence of arranging saidinlet and outlet in line, as specified, the governor does not require to be furnished with couplings to connect on the meter of the place, but may be furnished simply with pipe-nipples, and a portionv of gas-connection is removed to admit said nipples, between which it may be simply clamped to the gas connection or pipe. The gas entering the governor passes through the passage K into the inlet L of the pipe F, and in passing through said pipe the condensed portion may be readily removed by opening the drip cock or plug lVI. The gas passing 'through the outlet E from the pipe F flows into the space N over the liquid and tloat D into the passage H to the outlet H ofthe governor. The pressure and liquid in the space N is counterbalaneed by the atmosphere and liquid in the space I; but a pressure of the gas in the Space N varying from that for which the governor` is regulated causes either a dropping or rising of the float vand valve C, and consequently the opening or closing more or less of the valve, which will regulate the supply ofgas to the delivery-chamber N,thereby maintaining the pressure at which the governor is The valve C has on its top portion a guide-rod, O, and in the cap B is fitted a threaded vertical tubular guide, I7 in which the rod O is liberally guided. The upper end ofY uid. rlhe valve is set according to the height of the glycerine in the chamber. During the proper action of the governor stud Q does not rise out of the slot X; but Whenever the governor is desired to be put out of operation the cap It, secured over the guide and guiderod O upon the cap B, is removed. The rod by its top button is raised with the iloat until the stud Q is passed out of the slot X, and then it is turned to rest upon the top end of the guide I). By this means the iloat and valve are put out of operation, and the governor allows the gas to pass through it without hinderance and regulation as if the governor kWere not employed and entirely out of action.

So as to test and measure the amount of gas consumed ungoverned and compare the same with the governed gas-pressure, and to determine if or not a saving of gas is attained, the siphon-shaped gas-conducting pipe F is made of smooth metal to pass the gas with little friction and loss of pressure. The glyeerine-oil regulating-liquid does not rapidly form solid sediment accumulating on the float and thereby alter the action with the governor-valve and seat, as is the case with the mercury regulating-liquid.

S represents a pipe forinserting the liquid.

The case A is made and jointed with a iiat cap, T, having a vertical joint, V, and is thereon bolted, as shown. A

What I claim as my invention isl. In a pressure-regulating governor', the combination of the two-compartment or siphon case containing' a fluid with a siphon gas-pipe Within said case, and provided With a drip-pipe, substantially as described.

2. In a. pressure-regulating governor, the combination of the twocompartment or siphon case containing a luid with a siphon gas-pipe Within said case and a float-valve for regulating the outlet of said pipe, substantially as described.

3. In a tluid-pressure regulator, the combination of the valve-rod provided with a stud with the slotted guide, substantially as shown.

4. In a. fluid-pressure regulator, the combination ofthe two-compartment or siphon case containing a fluid, the outer one of which connects with the atmosphere and the inner one with the delivery-pipe, with a siphon gaspipe Within said case, the drip-eock, iioat, and valve, substantially as and for the purpose set forth.

5. In a fluid-pressure regulator, the com-y bination of the two-compartment or siphon ease containing a fluid with a siphon gas-pipe within said case, the drip-cock, the Iioat, the valve, and rod, the guide, .andthe two caps, Substanti ally as and for the purpose described.

In testimony whereofl I hereunto set my hand this 2d day of October, 1884.
